For my house hack I'm coming out way ahead compared to renting an apartment even though I paid full retail for an MLS property.

You're doing a great job planning ahead. 

And, I've had a few minor issue that bit me, but overall, WAY ahead.

If that goes well, I'd look to doubling that every year (but I don't want to get too ahead of myself).

The guy had moved out two months ahead of end of lease, took the internet which made watering non existent (smart wifi watering).

Not that you can't do it, just have those conversations ahead of time so you know what your options are and always have multiple exit strategies.My wife and I host a virtual meetup and we did about an hour on BRRRR refinancing a couple months ago if you want an overview.

HELOC can get closed down by lender if market goes southNON owner cash out refinance is expensive today as to the risk lenders see ahead. 

Thanks ahead of time! 

You have the right idea of how to market.As a broker, I encourage sellers to get a phase 1 before we go to market - that way we know ahead of time if there is any remediation and can either fix it ahead of time or price in the work.
